Carbide doesn't weld too good. I tried it once at a customers request, used a blank from a broken Boring Bar and tig welded a stainless bead up the side, as soon as the weld started to cool the section with the weld broke out landing several inches away on the bench. I haven't looked at a Carbide saw chain, are the teeth silver soldered on like some machine tools?
 
Thats what I was afraid of, the hardfacing rod would not stick to the carbide. The carbide must be to hard and or dirty to mix the two metals to bond together.

The silver brazing solder 50-N is what I use to bond carbide teeth to the steel.
As far as I know the chainsaw carbide teeth are silver soldered in so you must be able to retip them.?
I have welded on carbon steel with a cobalt hardfacing welding rod with no problem,
either gas or tig welding with cobalt can be used to rebuild a carbon saw tooth, and be sharpen down to a razor edge.

Picture of a brazed slasher saw tooth with silver solder 50-N bonded to a .500 k carbide,
Dose anybody have a close up picture of a carbide chain we can look at.

I used to use 4130 air hardening tig rod on machine tools, If I remember right it would be about 43 rc. I don't remember the exact mix in silver solder
we used on carbide but it was high in silver so we had to use a higher temp. flux with it to avoid burn off before the silver flowed. It would be worth a try if you could find a beat up chain and try retipping.
 
I am looking for a chain now to experiment on, I will first try to weld on the cobalt based number 12 hardfacing rod on a standard steel tip, and then sharpen. I will try carbide next.

i never tried full carbide chain. however i did try the injecta-sharp chain from baileys. the chain is made by carlton. i was not impressed by it at all. cut extremely slow and way too tough to sharpen unless you have a grinder. i'll stick with oregon lgx.
 
How can I cut faster with a carbide chain , and why does carbide teeth chains cut slow,??

Could it be the carbide teeth that can not hold a superior razor edge so making the tooth roll over the top of the wood instead of cutting through, could that be the main problem here ??

The manufacturers may not have a clue about what grade of carbide is the best to use,
all I here is c-2 carbide, there is a lot better grades of carbides out their then c-2 ? ?:dizzy:

My next project is to research and develop an alloy called (high speed carbide),
to improve faster chainsaw cutting ,
and edge holding abilities. That would be some what easy to sharpen.
I will keep you posted on the progress.

.... keep in mind that if you increase the life of the saw teeth you must also increase the life of the driver to match or else theres not much use in it,keep us posted there must be a combination that works

Checkout sub micron carbide or CBN //Sandvik carbide get the $$$$ out
 
sandvik , good carbide. I have come to the conclusion that a high speed CARBIDE will be like high speed STEEL with TUNGSTEN material , keeping in mind the best quality & value. Still engineering & field testing for chain saws & re-tipping teeth. Getting closer to the final product.

I have some trees you can come over and buck if you need test material.:greenchainsaw:
 
Thanks for the invite , I'll keep that in mind. I'm working on repairing chain saw teeth , I don't know yet if this is cost effective to do or not. Is there anybody you know of ever try to rebuild chain saw teeth.???
